make clean question

HarryBoy · 02-14-2011, 06:25 AM

When I run:
make -f mymakefile clean I get:
rm -f mybinary *.so.* *.dep *.o mybinary.sym

and all the above files are removed from the current directory.

But I have a directory /src/ where I have all my source files located. The *.o file in this directory are not removed?

How can I get these to be removed when I do a clean?

Have you tried make distclean?

make -f mymakefile distclean

gives me this error:
make: *** No rule to make target `distclean'. Stop.

Is there no way to do it simply with 'clean'??
Can I put someting in my make file to tell it to recurse into my /src/ folder???

Try something extremely basic like:

Code:

clean :
        $(RM) src/*.o

However, I'm a bit surprised that your Makefile does not have an alias for the object files that you want removed. Here's a real simple Makefile (for a C project) where the source code is in the src/ directory:

Code:

APP     = myapp

SRCS    = $(wildcard src/*.c)
OBJS    = $(SRCS:.c=.o)

CFLAGS  = -Wall -pedantic -c

LDFLAGS =

.PHONY: all clean distclean


all : $(APP)

$(APP) : $(OBJS)
        $(CC) $^ $(LDFLAGS) -o $@

%.o : %.c
        $(CC) $(CFLAGS) $^ -o $@

clean :
        $(RM) $(OBJS)

distclean : clean
        $(RM) $(APP)

I added:
CLEANFILES= src/*.o

to my make file and it now works:

make -f mymakefile clean
rm -f mybinary *.so.* *.dep *.o mybinary.sym src/*.o

thanks, your comments helped me understand this.
